The thesis is focused on the topic of street art as a phenomenon that encompasses different cultural and social domains. Its importance for the development of these same domains is undeniable, which will additionally be shown by the evolution of the same skill throughout history. From architecture to graphic design and art to social interventions through the acts of marketing or activism, street art has played a huge role in the expression and popular culture of urban residents. With the growth of cities, but also the development of smaller towns, the need for this kind of artistic activity has never been more meaningful. Regardless of the eternal opposition to the notion of classical art or degradation through comparisons with vandalism, street art is the interaction of man with his environment that goes beyond many established rules and laws. This makes the message clear and transparent. It is an intervention. The call for the action of creative minds whose limits are pushed only by imagination and the willingness to realize it. In order to overcome clichés and exaggerations or distortions of the image of street art, apart from the detailed theoretical part, we will also place everything absorbed in the context of practice, in which a methodological approach to such a topic will help us. The review will be based on the experiences of consumers, as well as authors of street art. The main tools during this process will be an in-depth interview and a survey, but a content analysis will also be set up so that the entire research can be rounded off with content beyond our borders of culture, time and space. With the analysis of theory and practice, its congruence and cognitions, we will conclude the thesis and question, confirm or deny the hypotheses given during the research itself. With such an approach, we will get a clear and consistent picture of street art as a social intervention.
